When you switch to your hi beam, the bulb itself moves to shoot it at a higher angle. That is all. It is the exact same bulb, exact same brightness, exact same power, etc...as the lo beam. Just now shooting at a higher angle to give you a hi beam.

People don't realize how much light goes out if you reflect the bulb up and/or move a reflector and it just throws light everywhere!
